Study Notes

Digital Devices and Software

  • Digital devices consist of physical components referred to as hardware.
  • Hardware devices cannot function without software.

Software

  • Software is a set of instructions that tell digital devices what to do and how to do it.
  • Software can also be referred to as programs or software programs.
  • Software is classified into two categories: Systems Software and Application Software.

Systems Software

  • Systems software is a set of instructions that control the general running of a digital device.
  • It is designed to operate, maintain, and control computer hardware and provide a platform for running application software.
  • There are two categories of system software: Operating Systems and Utility Programs.

Operating Systems

  • An Operating System (OS) is a software that allows a user to use, control, and manage the hardware of a digital device.
  • It provides a platform to run other system software and application software.
  • It is the most important software on any device, without which, the device won't function.
  • Examples of Operating Systems include:
    • Windows Operating System (Windows 10, 8.1, 8, 7, XP, 98)
    • Android
    • Linux
    • iOS
    • Unix

Types of Operating Systems

  • Single-user OS: allows only one user to access the computer at a time
  • Multi-user OS: allows multiple users to access the computer at the same time
  • Single-tasking OS: allows a user to perform only one task at a time
  • Multi-tasking OS: allows a user to perform multiple tasks simultaneously
  • Network OS: provides additional functionality for networked computing, including user authentication, file sharing, and network resource management

Functions of the Operating System

  • Provides a user interface to interact with the computer
  • Manages application software, starting and stopping programs as needed
  • Manages files, including saving, organizing, and loading
  • Manages system resources, including memory and CPU allocation
  • Handles errors that occur during program execution or data transfer
  • Manages printer spooling, allowing multiple tasks to print on the same printer
  • Manages input and output hardware, including accepting input and sending output to devices

Security Features

  • Manages system security, including monitoring and restricting access
  • Prevents malicious files or users from damaging the system
  • Provides firewall protection to block malicious files or people
  • Manages user accounts and passwords
  • Provides file and disk encryption
  • Sets file permissions (e.g., read, write, read-only)
  • Manages file access and sharing settings
